The utility model discloses utilize the remote control device, replace the operating condition of artifical control impeller feeder, practice thrift the cost of labor, improve personnel operational environment, the conservation work personnel are healthy to can make the fail safe nature of system obtain improving.
Description
Technical field
The utility model relates to technical field of industrial automatic control, specifically a kind of paddle coal feeder remote control.
Background technology
Paddle coal feeder is the important equipment in the coal handling system of fuel-burning power plant, there is no the paddle coal feeder system that Long-distance Control designs, because equipment operation condition is complicated, accident is many, easily cause equipment failure, having to adopt local manual operation's mode, the personnel of arranging work follow paddle coal feeder walking, monitor the operation condition of paddle coal feeder at any time. Thus force in the underpass of staff's dust sombre in humidity, high and work, neither meeting environmental requirement, increase again human cost, harm staff is healthy.
There is following problem and shortcoming in prior art:
(1) paddle coal feeder operation condition is complicated, often there will be big block foreign material, as: stone, wood, iron block etc., it is easy to cause paddle coal feeder fault.
(2) in coal receiving bunker, dust is many, humidity big, when paddle coal feeder can not realize distant place control, operation personnel can only be arranged to follow paddle coal feeder walking, and harm staff is healthy.
(3) the electric loop of closed loop control system is complicated, and equipment failure is difficult.
(4) paddle coal feeder adopt holder cable mode for equipment electrical source of power, control and feedback states be provided time, cable, owing to dragging frequent distance, often causes cable to draw bad, and equipment failure is many.
(5) position signal of paddle coal feeder adopts proximity switch, reads DI signal, and when carrying out configuration mode in logic, judgment device travel position, exists loss or the problem of many samplings, cause can not accurately determining equipment position due to DI signal.
(6), when paddle coal feeder works, it is necessary to open whole bar coal receiving bunker intraoral illumination, there is waste energy problem.
Practical novel content
The utility model is in order to solve the problem of prior art; provide a kind of paddle coal feeder remote control; replace the working order of manual monitoring paddle coal feeder; save cost of labor, improve person works's environment, protect staff healthy, and system security reliability can be made to be improved.
The utility model comprises coal conveyer belt and paddle coal feeder, described paddle coal feeder is provided with paddle coal feeder controlling box, paddle coal feeder controlling box is connected with far-end controlling box by power trolley, and far-end controlling box is connected with the operation station in combustion fortune watch-keeping cubicle by optical cable. Wireless video monitoring system replaces the working order of manual monitoring paddle coal feeder, saves cost of labor, improves person works's environment, protects staff healthy. Owing to adopting power trolley to replace conventional slip cable guide mode (being commonly called as " holder cable " mode), solve power cable and easily draw bad, the many problems of fault.
Improving further, described paddle coal feeder controlling box comprises PLC and near-end carrier modem, and far-end controlling box comprises far-end carrier modem, and near-end carrier modem is connected with far-end carrier modem by power trolley. Power carrier control system thoroughly solves conventional slip cable guide (" holder the cable ") problem that the system fault is many, and repair and maintenance is convenient, maintenance cost much slower, and system security reliability improves.
Improving further, described paddle coal feeder controlling box is provided with camera and set lights. Illumination Design, on paddle coal feeder body, follows paddle coal feeder walking, without illumination dead angle, avoids standard-sized sheet coal receiving bunker to throw light on, brownout, and the more long energy-saving effect of coal receiving bunker is more obvious.
Improving further, described coal conveyer belt is provided with position coder. Paddle coal feeder accurate positioning, facilitates operator control paddle coal feeder work area, it is to increase the security that equipment runs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Long-distance Control and the signal feedback schematic diagram of paddle coal feeder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation, comprise coal conveyer belt and paddle coal feeder, described paddle coal feeder is provided with paddle coal feeder controlling box, paddle coal feeder controlling box is connected with far-end controlling box by power trolley, and far-end controlling box is connected with the operation station in combustion fortune watch-keeping cubicle by optical cable. Wireless video monitoring system replaces the working order of manual monitoring paddle coal feeder, saves cost of labor, improves person works's environment, protects staff healthy. Owing to adopting power trolley to replace conventional slip cable guide mode (being commonly called as " holder cable " mode), solve power cable and easily draw bad, the many problems of fault.
The Long-distance Control of paddle coal feeder and signal feedback schematic diagram are as shown in Figure 2, paddle coal feeder controlling box comprises PLC and near-end carrier modem, far-end controlling box comprises far-end carrier modem, and near-end carrier modem is connected with far-end carrier modem by power trolley. Power carrier control system thoroughly solves conventional slip cable guide (" holder the cable ") problem that the system fault is many, and repair and maintenance is convenient, maintenance cost much slower, and system security reliability improves.
Paddle coal feeder controlling box is provided with camera and set lights. Illumination Design, on paddle coal feeder body, follows paddle coal feeder walking, without illumination dead angle, avoids standard-sized sheet coal receiving bunker to throw light on, brownout, and the more long energy-saving effect of coal receiving bunker is more obvious.
Coal conveyer belt is provided with position coder. Paddle coal feeder accurate positioning, facilitates operator control paddle coal feeder work area, it is to increase the security that equipment runs.
Paddle coal feeder employing central control desk and on the spot manual operation two kinds of control modes:
1, local operation pattern: user beats housing switch " on the spot ":
1) by the operation push-button control movable motor such as " advance ", " retrogressing " " stopping ", it is achieved the advance and retreat of paddle coal feeder stop control.
2) coal motor " start and stop " button is dialled by operation, it is achieved paddle coal feeder dials coal function.
